Answer:

The least common denominator is 21.

Explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:


(1)/(3) ×
(7)/(7) =
(7)/(21)
(3)/(7) ×
(3)/(3) =
(9)/(21)
